DEPARTMENT OF TRANSPORTATION

14 CFR Part 39

[Docket No. 93-NM-69-AD; Amendment 39-8886; AD 94-08-14]

Airworthiness Directives; Corporate Jets Limited Model BAe 125-

1000A Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This amendment adopts a new airworthiness directive (AD),

applicable to all Corporate Jets Model BAe 125-1000A series airplanes,

that requires replacement of the white `EMERG CONTCTRS' annunciator

screen on roof panel `CG' of the flight deck with an amber screen. This

amendment is prompted by a report that the annunciator screen currently

installed on these airplanes is not a color that would alert the flight

crew that corrective action may be necessary. The actions specified by

this AD are intended to ensure that the flight crew is alerted to

conditions when standby electrical power is not available.

DATES: Effective May 20, 1994.

The incorporation by reference of certain publications listed in

the regulations is approved by the Director of the Federal Register as

of May 20, 1994.

ADDRESSES: The service information referenced in this AD may be

obtained from Corporate Jets, Inc., 22070 Broderick Drive, Sterling,

Virginia 20166. This information may be examined at the Federal

Aviation Administration (FAA), Transport Airplane Directorate, Rules

Docket, 1601 Lind Avenue, SW., Renton, Washington; or at the Office of

the Federal Register, 800 North Capitol Street NW., suite 700,

Washington, DC.

FOR FURTHER INFORMATION CONTACT: Stephen Slotte, Aerospace Engineer,

Standardization Branch, ANM-113, FAA, Transport Airplane Directorate,

1601 Lind Avenue, SW., Renton, Washington 98055-4056; telephone (206)

227-2797; fax (206) 227-1320.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal

Aviation Regulations (14 CFR part 39) to include an airworthiness

directive (AD) that is applicable to all Corporate Jets Model BAe 125-

1000A series airplanes was published in the Federal Register on

November 29, 1993 (58 FR 62557). That action proposed to require

replacement of the white `EMERG CONTCTRS' annunciator screen on roof

panel `CG' of the flight deck with an amber screen.

Interested persons have been afforded an opportunity to participate

in the making of this amendment. No comments were submitted in response

to the proposal or the FAA's determination of the cost to the public.

The FAA has determined that air safety and the public interest require

the adoption of the rule as proposed.

The FAA estimates that 13 airplanes of U.S. registry will be

affected by this AD, that it will take approximately 1 work hour per

airplane to accomplish the required actions, and that the average labor

rate is $55 per work hour. Required parts will be supplied by the

manufacturer to operators at no cost. Based on these figures, the total

cost impact of the AD on U.S. operators is estimated to be $715, or $55

per airplane.

The total cost impact figure discussed above is based on

assumptions that no operator has yet accomplished any of the

requirements of this AD action, and that no operator would accomplish

those actions in the future if this AD were not adopted.

The regulations adopted herein will not have substantial direct

effects on the States, on the relationship between the national

government and the States, or on the distribution of power and

responsibilities among the various levels of government. Therefore, in

accordance with Executive Order 12612, it is determined that this final

rule does not have sufficient federalism implications to warrant the

preparation of a Federalism Assessment.

For the reasons discussed above, I certify that this action (1) is

not a ``significant regulatory action'' under Executive Order 12866;

(2) is not a ``significant rule'' under DOT Regulatory Policies and

Procedures (44 FR 11034, February 26, 1979); and (3) will not have a

significant economic impact, positive or negative, on a substantial

number of small entities under the criteria of the Regulatory

Flexibility Act. A final evaluation has been prepared for this action

and it is contained in the Rules Docket. A copy of it may be obtained

from the Rules Docket at the location provided under the caption
